Fluidics and physics – scientifically explained

Physics – the natural science per se

Physics is the area of natural sciences that studies fundamental knowledge and phenomena of nature. The origin of physics goes back to man’s desire to understand the processes of nature, to be able to explain them with common laws and, by doing so, make use of nature. Physics can basically be divided into two areas: while in experimental physics, findings on the laws of nature are gained by observation and experience, this is done by mathematics and logics in theoretical physics.

As a law of nature, physics creates a connection between biology and chemistry and explains phenomena of energy and matter. Medicine started working with the laws of physics at an early stage. In the recent past, medical physics has appeared, among other areas, in biophysical methods in radiotherapy and nuclear medicine, in X-ray diagnosis, in imaging processes such as computer tomography or magnetic resonance imaging as well as ophthalmic surgery.

Fluidics – a powerful instrument

Fluidics – sometimes also referred to as fluidic logic – is the application of a fluid to perform analogue or digital operations that are related to electronic processes. The physical basis of fluidics is pneumatics and hydraulics, based on the theoretical foundation of fluid dynamics, a branch of fluid mechanics. The term fluidics is normally used when devices have no moving parts – common hydraulic components such as hydraulic cylinders and control valves are therefore not considered as fluidic devices in general.

It is especially in eye surgery that fluidics – provided that you master it –  can make optimum use of its special talents. Thanks to the combination of electro-mechanical devices and fluidic properties, more precise flow control and fluidic management is achieved. With work on the eye, this distinct degree of control and precision is of decisive importance.
